ORDER
Adopted:  September 29, 2023 Released:  September 29, 2023
By the Chief, Wireless Telecommunications Bureau:
I. INTRODUCTION
1. Today we grant a limited waiver of section 20.19(b)(1) and (b)(3) of the Commission’s 
wireless hearing aid compatibility rules with respect to the volume control technical standard that 
handset manufacturers use in part to certify handsets as hearing aid-compatible under the 2019 ANSI 
Standard.1  Our action is prompted by a request filed by the Alliance for Telecommunications Industry 
Solutions (ATIS) seeking waiver of certain aspects of these rules.2  Under the terms of the time-limited 
waiver we grant today, a handset may be certified as hearing aid-compatible under the 2019 ANSI 
Standard if it meets the volume control testing requirements described in this Order as well as all other 
aspects of the 2019 ANSI Standard.
2. Consistent with ATIS’s September 12, 2023, ex parte letter (ATIS Ex Parte Letter) and as 
a condition of this waiver, we require a handset to pass the conversational gain test at the 2 Newton (N) 
force level on all available narrowband and wideband codecs and air interface combinations.3  With 
respect to the 8N force level test, we agree with the ATIS Ex Parte Letter that this test should be 
performed, and we waive the requirement that a handset achieve at least an 18 dB conversational gain.4  
This waiver is conditioned on manufacturers performing the 8N force level test using the same testing 
parameters that we are requiring for the 2N force level test and to place on the handset’s package label 
the resulting conversational gain (even if it is below 18 dB) in a manner consistent with our existing 
hearing aid compatibility labeling rules.
3. With respect to the related receive distortion and noise performance (distortion/noise) and 
receive acoustic frequency response performance (frequency response) tests, we agree with the ATIS Ex 
Parte Letter that handsets must pass testing using at least one narrowband and one wideband codec of the 
1 The 2019 ANSI Standard refers to the technical document entitled Accredited Standards Committee C63®–
Electromagnetic Compatibility, American National Standard Methods of Measurement of Compatibility Between 
Wireless Communications Devices and Hearing Aids, ANSI C63.19-2019 (approved Aug. 19, 2019) (2019 ANSI 
Standard).
2 Petition of ATIS on Behalf of the Covered Entities of the Hearing Aid Compatibility Task Force for Limited, 
Interim Waiver, WT Docket Nos. 15-285 and 20-3 (filed Dec. 16, 2022) (ATIS Waiver Petition).  ATIS filed its 
waiver petition on behalf of all manufacturers and service providers subject to section 20.19(b)(1) and (b)(3) of the 
Commission’s wireless hearing aid compatibility rules.  Id. at 1, 4.

2manufacturer’s choosing.5  We also accept ATIS’s suggestion that at least one narrowband and one 
wideband codec must pass testing for distortion/noise and frequency response and tests will be limited to 
one bit rate and only with those air interfaces associated with the chosen codecs and that the other codecs 
used for conversational gain at the 2N and 8N force levels are not required to undergo the 
distortion/noise and frequency response tests.6  Further, as detailed below, we accept ATIS’s suggested 
method to set the volume control setting for testing these other codecs for conversational gain.7
4. By taking these steps, we ensure that when the exclusive use transition period ends on 
December 5, 2023, new handset models can be certified as hearing aid-compatible using the 2019 ANSI 
Standard as modified by the conditions established in this Order.8  Our actions allow consumers with 
hearing loss who use hearing aids or cochlear implants to benefit from wider availability of handsets 
offering improved hearing aid compatibility under the 2019 ANSI Standard’s radio frequency (RF) 
interference and inductive coupling requirements.  In addition, our approach gives consumers assurance 
that a handset’s amplifier/speaker combination will provide improved volume control functionality over 
narrowband and wideband modes of voice communications, and that consumers have the information 
that they need to make informed purchasing decisions.  Our actions today will move us closer to the 
Commission’s goal of reaching 100% hearing aid compatibility for wireless handsets, while also creating 
a path forward for testing to ensure that handsets have volume control capabilities.9
5. This waiver is effective immediately upon release of this Order so that manufacturers 
may afford the benefits of this relief to consumers with hearing loss as soon as feasible.  In reliance upon 
ATIS’s representations that efforts are underway to expeditiously develop a new volume control 
standard through the TIA standards setting process, we limit this waiver to a two-year period.10  During 
this waiver period, we will evaluate the effectiveness of the waiver standard in meeting the needs of 
consumers with hearing loss and take action where appropriate.  We expect that a two-year time 
limitation for the waiver will encourage all interested parties to work together to rapidly develop an 
improved volume control standard that we can incorporate into our rules in the future.  To ensure this 
outcome, we condition this waiver in part on ATIS filing a status letter on the development of a new 
5 ATIS Ex Parte Letter at 2.  Originally, ATIS had proposed that handsets would only have to pass testing using one 
narrowband or one wideband codec in combination with any air interface.  ATIS Waiver Petition at 4, 12-13.

at the 2N and 8N force levels.  Id. at 2 & n.5.

II. BACKGROUND
6. The Commission’s wireless hearing aid compatibility rules require handset manufacturers 
to ensure that at least 85% of the total number of handset models that they offer are certified as hearing 
aid-compatible.12  Handsets are considered to be hearing aid-compatible if they meet certain ANSI 
technical standards that the Commission has incorporated by reference into the wireless hearing aid 
compatibility rules.13  Before 2017 the Commission’s wireless hearing aid compatibility rules addressed 
acoustic and inductive coupling,14 but in 2017 the Commission modified its wireless hearing aid 
compatibility rules by adopting a volume control requirement similar to the requirement for wireline 
phones.15  The Commission determined that the objectives of section 710 of the Communications Act 
would be served by modifying the Commission’s acoustic coupling provisions for wireless handsets to 
include a volume control requirement designed to accommodate consumers with hearing loss who use 
hearing aids or cochlear implants and those with hearing loss who do not use these devices.16  The 
Commission affirmed its belief that a volume control requirement that specifies certain levels of 
amplification as an element of hearing aid compatibility is just as necessary for wireless handsets as it is 
for wireline phones in order to ensure the provision of effective telecommunication services for people 
with hearing loss.17
7. While the Commission adopted a wireless volume control requirement in 2017, the 
Commission did not adopt a specific wireless volume control technical standard.  Instead, the 
Commission noted that an industry approved technical standard was nearing completion and, once the 
Commission adopted this standard into its rules, compliance with this standard would constitute 
compliance with the Commission’s new wireless volume control requirement.18  The Commission 
suggested that this standard could include: (1) the use of conversational gain for measuring receive 
loudness; (2) the establishment of minimum value(s) for the acceptable maximum volume(s); (3) the use 
of a Head and Torso Simulator (HATS); and (4) the use of two force levels for holding the handset next 
to the ear—2N force for people who use hearing aids, and 8N force for people who do not use hearing 
aids.19
11 See infra para. 37.

13 47 CFR § 20.19(b).
14 Hearing aids operating in acoustic coupling mode receive sounds through a microphone and then amplify all 
sounds surrounding the user, including both desired sounds, such as a handset’s audio signal, and unwanted ambient 
noise.  To use a wireless handset with a hearing aid or cochlear implant in acoustic coupling mode, radiofrequency 
interference and other electromagnetic interference from the handset must be controlled.  Hearing aids operating in 
inductive coupling mode turn off their microphone to avoid amplifying unwanted ambient noise, instead using a 
telecoil (T-Coil) to receive only audio signal-based magnetic fields generated by inductive coupling-capable 
telephones.  The hearing aid converts these fields back to sound or to a signal appropriate for cochlear implant users.

48. In September 2019, the ANSI Committee20 petitioned the Commission to replace the 
existing 2011 ANSI Standard21 referenced in the Commission’s rules for handset certification with the 
new 2019 ANSI Standard.22  The ANSI Committee oversees the development of the ANSI wireless 
hearing aid compatibility technical standard, and the committee is composed of handset manufacturers 
and testing laboratories, among other groups.23  While the 2011 and the 2019 ANSI Standards address 
acoustic and inductive coupling between wireless handsets and hearing aids, the new standard also 
includes the wireless volume control technical standard referenced by the Commission in 2017.  The 
2019 ANSI Standard specifically incorporates by reference the TIA 5050 Standard for volume control 
and requires handsets to meet this standard along with the rest of the 2019 ANSI Standard in order for a 
handset to be certified as hearing aid-compatible under this standard.24
9. The TIA 5050 Standard establishes a volume control testing methodology which defines 
conversational gain as the acoustic output level of speech from a handset relative to the acoustic level 
that would be present in a face-to-face conversation with two people one meter apart.25  To be compliant 
with this standard, a handset must undergo testing at 2N and 8N force levels with each force level 
requiring the passing of three interrelated tests.26  The 2N test requires a handset to demonstrate at least 6 
dB of conversational gain while also meeting certain distortion/noise and frequency response 
requirements.27  The 8N force level test requires a handset to demonstrate at least 18 dB of 
conversational gain while also meeting the same distortion/noise and frequency response requirements.28
10. In February 2021, the Commission adopted the 2019 ANSI Standard and the related TIA 
5050 Standard and made these standards the exclusive wireless hearing aid compatibility certification 
standards after a two-year transition period that at the time was set to end on June 5, 2023.29  In adopting 
the 2019 ANSI Standard, the Commission noted that this standard was broadly supported by both

5industry and consumer groups.30  Further, the Commission observed that the 2019 ANSI Standard “for 
the first time . . . incorporates a volume control requirement that will provide significant benefits to 
persons with hearing loss, whether or not they use hearing aids.”31
11. On December 16, 2022, ATIS filed a petition requesting that we grant a limited interim 
waiver of section 20.19(b)(1) and (b)(3) of the Commission’s wireless hearing aid compatibility rules for 
all entities subject to these rules to allow handsets to be certified under the 2019 ANSI Standard as 
hearing aid-compatible using a reduced volume control testing methodology.32  ATIS asserts that the 
existing volume control testing standard is fundamentally flawed because it uses a pulsed-noise signal, 
which it claims is insufficiently voice-like to be compatible with many modern codecs.33  ATIS states 
that the standard’s use of a pulsed-noise signal resulted in none of the handsets that it tested passing the 
standard.34
12. ATIS’s Waiver Petition requests that the Commission allow handsets to be certified as 
hearing aid-compatible if they meet the 2019 ANSI Standard’s acoustical and inductive coupling 
standards in full and meet a reduced volume control standard that would only require a handset to: (1) 
pass conversational gain for all available codecs and air interface combinations at the 2N level, and (2) 
obtain passing results for at least one of the handset’s available codecs for the distortion/noise and 
frequency response requirements.35  Additionally, it requests that we limit the codecs to be tested to those 
that are within the scope of the TIA 5050 Standard, which includes narrowband and wideband codecs, 
and that we completely waive the 8N force level test.36  Finally, it requests that the waiver remain in 
place until the new volume control technical standard that is being developed through the TIA process 
becomes effective.37
13. At the same time that ATIS filed its waiver petition for a reduced volume control testing 
standard, the HAC Task Force filed its Final Report setting forth its recommendations for how the 
Commission can achieve its goal of requiring that all new handsets be certified as hearing aid-
compatible.38  The HAC Task Force is an independent organization composed of groups who represent 
the interests of people with hearing loss, wireless service providers, and wireless handset manufacturers 
that formed for the purpose of reporting to the Commission on whether requiring 100% of new handsets 
to be certified as hearing aid-compatible is an achievable objective.39  Part of the HAC Task Force’s 
Final Report on how the Commission can achieve its 100% objective includes a recommendation that the 
Commission adopt ATIS’s reduced volume control testing methodology and maintain it until the 
30 2021 HAC Report and Order, 36 FCC Rcd at 4567, para. 2.

6Commission has an opportunity to adopt a new volume control standard that is presently being 
developed through the TIA process.40
14. Similarly, ATIS’s waiver petition cites data from the HAC Task Force’s Final Report to 
support its description of the issues experienced in relation to the testing methodology for volume 
control.41  Testing data included in the HAC Task Force’s Final Report indicates that for the 
distortion/noise test the pulse noise signal passed through the Adaptive Multi-Rate (AMR) codec to 
produce unintended noise and distortion of the signal.42  Conversely, testing data included with the Final 
Report indicates that this problem did not exist when testing was conducted on the Enhanced Voice 
Services (EVS) codec.43  As a potential solution, the Final Report indicates that the TIA 5050 Standard’s 
requirement that testing be done using any air interface but generally limited to using the AMR codec 
could be modified or reinterpreted to allow any codec and air interface combination to be used for the 
distortion/noise and frequency response measurements.44
15. On March 23, 2023, the Wireless Telecommunications Bureau (Bureau) released a Public 
Notice seeking comment on ATIS’s waiver petition that established a 45-day comment period that 
closed on May 18, 2023.45  The Public Notice sought comment on ATIS’s waiver petition within the 
context of the Commission’s commitment to attaining 100% hearing aid compatibility for all covered 
wireless handsets, as soon as achievable,46 as well as the Commission’s previous finding that a volume 
control requirement is necessary “to ensure the provision of effective telecommunications for people 
with hearing loss.”47  In addition to seeking comment on ATIS’s waiver petition, Commission staff have 
met on an ex parte basis with the HAC Task Force on multiple occasions and with the Hearing Loss 
Association of America (HLAA).48  HLAA claims to be “the nation’s leading organization representing 
consumers with hearing loss,”49 serves as Co-Chair of the HAC Task Force, and supports the HAC Task 
Force Final Report recommendations.50
40 Id. at ii, 18, 21-22.  The Final Report specifically references ATIS’s waiver petition and states that the 
Commission should grant the petition and allow “wireless handsets to meet a modified volume control test that 
ensures increased amplification for hearing device users until the TIA 5050 standard has been revised and adopted 
into the FCC’s rules.”  Id. at ii.  Given ATIS’s waiver request, the Final Report does not recommend a handset 
model deployment benchmark for volume control.  Id. at 19.

716. On April 14, 2023, the Bureau released an order extending the transition period for 
exclusive use of the 2019 ANSI Standard and the related TIA 5050 Standard from June 5, 2023, as 
originally established by the Commission, to December 5, 2023.51  The Bureau took this step to ensure 
that handset manufacturers can continue to certify new handset models with hearing aid compatibility 
features under the 2011 ANSI Standard while the Commission considers ATIS’s waiver petition.52  The 
Bureau stated that continuing to allow new handset models to be certified as hearing aid-compatible is 
essential as the Commission moves to its goal of all handsets being hearing aid-compatible.53
17. Finally, in the ATIS Ex Parte Letter, ATIS reiterates and clarifies its volume control 
testing proposals contained in its waiver petition, and partially revises its proposals.54  Consistent with its 
original proposal, ATIS reiterates its suggestion that testing at the 2N force level should require passing 
of conversational gain for all available narrowband and wideband codecs and air interface combinations.  
With respect to the 8N force level test, however, ATIS modifies its original proposal and suggests that 
testing at this force level be done on all available narrowband and wideband codecs and air interface 
combinations; but that the requirement of at least an 18 dB conversational gain passing rate be waived; 
and that the resulting conversational gain from testing be placed on the handset’s package label.  Further, 
ATIS suggests a modification for its proposal for the distortion/noise and frequency response tests.  It 
proposes obtaining “passing results for at least one of the device’s narrowband and one wideband codecs 
for the distortion and frequency response,” instead of its original suggestion that a passing result would 
only have to be obtained for one narrowband or one wideband codec.55  ATIS clarifies, however, that 
testing of the chosen narrowband and wideband codecs for the distortion/noise and frequency response 
tests should be limited to one bit rate and only those air interfaces associated with the chosen codecs.  
Under its proposal, the other narrowband and wideband codecs used for the 2N and 8N force level 
conversational gain tests are not required to undergo distortion/noise and frequency response testing.56
III. DISCUSSION
18. Section 1.3 of the Commission’s rules provides that the Commission may “on its own 
motion or on petition” waive a rule “for good cause shown, in whole or in part, at any time.”57  The 
Commission may find that the “good cause shown” standard is met when: (1) “special circumstances 
warrant a deviation from the general rule” and (2) “such deviation will serve the public interest.”58  In 
this case, we find good cause to grant ATIS’s waiver request under the conditions discussed below.  
Further, we find that the underlying purpose of the rule would not be served by strictly applying all of 
the requirements at this time since such strict enforcement might have an effect of denying consumers 
most of the benefits of the latest standard.59  For this additional reason, we find it in the public interest to 
grant limited relief and, thereby, permit consumers with hearing loss to benefit from the advantages that

8the 2019 ANSI Standard offers beyond just volume control while at the same time ensuring some 
volume control benefits.
19. We find special circumstances exist that warrant a deviation from the general rule as well 
as the fact that strict compliance with the volume control testing standard at this time would undermine 
the general purpose of the hearing aid compatibility rules.  Specifically, ATIS asserts that there are 
“significant and material problems with the methodology used for testing volume control” that render 
compliance with the 2019 ANSI Standard functionally impossible given that the standard requires 
compliance with the TIA 5050 Standard.60  According to ATIS, the problem relates to section 
20.19(b)(3)(i) of the Commission’s wireless hearing aid compatibility rules even though handset 
manufacturers never addressed this rule in their filed comments when the Commission was considering 
adopting the 2019 ANSI Standard and the related TIA 5050 Standard.  This provision provides that “a 
handset is hearing aid-compatible if it meets the 2019 ANSI standard for all frequency bands that are 
specified in the ANSI standard and all air interfaces over which it operates on those frequency 
bands. . . .”61  In turn, the 2019 ANSI Standard specifies that in order for a handset to meet the standard’s 
volume control requirements the handset must meet the requirements of the TIA 5050 Standard.62  The 
TIA 5050 Standard specifies that handsets must be tested for volume control using one AMR 
narrowband codec and one AMR wideband codec or the next closest codec if the AMR narrowband or 
wideband codec is not available in combination with any available air interface of the manufacturer’s 
choosing that supports the codec being tested.63
20. While the TIA 5050 Standard generally limits testing to one AMR narrowband and one 
AMR wideband codec in combination with an air interface of the manufacturer’s choosing, ATIS asserts 
that this is not the case in practice because of the testing guidance the Office of Engineering and 
Technology (OET) Laboratory Division has issued.64  ATIS states that OET’s testing guidance 
effectively requires a handset to pass the Commission’s volume control standard on all available codecs 
and air interface combinations even though the TIA 5050 Standard does not specify this approach.65  
According to ATIS, this situation results from OET’s guidance requiring handset manufacturers to 
investigate and document “worst-case test conditions and results.”66  ATIS states that this all air 
interface/frequency/codec testing requirement results in a testing standard that handsets cannot pass 
because the TIA 5050 Standard does not use a speech-like signal that can pass substantially unchanged 
through all possible speech codecs.67

67 ATIS Waiver Petition at 10.  ATIS believes this problem has to do with the fact that the TIA 5050 Standard’s 
testing methodology was developed using pulsed-noise signals that are insufficiently voice-like to be compatible 
with many modern codecs.  Id. at 3-4, 10.Federal Communications Commission DA 23-914
921. In support of its argument, ATIS states that all of the handsets that it tested using the 
2019 ANSI Standard failed to pass this standard.68  Specifically, ATIS states that it tested eighteen 
handset models that had recently been certified as hearing aid-compatible using the 2011 ANSI Standard 
and all of these handsets failed to pass the 2019 ANSI Standard because of the Commission’s all air 
interface/frequency/codec testing requirement reflected in OET’s Knowledge Database (KDB) Volume 
Control Guidance document.69  According to ATIS, the tested handsets represented a range of handset 
models offered by manufacturers, with models being offered at a range of price points, having multiple 
form factors, and having multiple chip set providers.70
22. No party filed comments opposing ATIS’s request for a reduced volume control testing 
methodology on an interim basis until a full volume control testing methodology can take effect.71  
Commenters echo ATIS’s statement that the current volume control testing methodology is flawed and 
needs to be modified so consumers with hearing loss can benefit from other aspects of the 2019 ANSI 
Standard.72  The unanimous supporters of ATIS’s waiver request include HLAA, an advocacy 
organization which represents consumers with hearing loss.73  In addition to these comments, handset 
manufacturers’ most recent compliance filings reveal that not a single handset has been certified as 
hearing aid-compatible under the 2019 ANSI Standard.74  Rather, these reports indicate that all of the 
handsets that manufacturers are currently offering have been certified as hearing aid-compatible using 
the 2011 ANSI Standard.
23. Based on these special circumstances and the fact that the underlying purpose of our 
hearing aid compatibility rules would be frustrated by strict adherence to the volume control testing 
standard, we find it in the public interest to take action to ensure that handset manufacturers can certify 
handsets as hearing aid-compatible under the 2019 ANSI Standard and consumers with hearing loss can 
benefit from the advantages that the 2019 ANSI Standard offers, including some volume control 
benefits.  While ATIS is requesting that we waive certain aspects of the volume control testing 
methodology as an interim measure, ATIS is not requesting a waiver of the 2019 ANSI Standard’s 
acoustic and inductive coupling requirements.  We agree with ATIS and commenters that by waiving 
certain aspects of the volume control testing methodology, we allow consumers who use hearing aids or 
cochlear implants to receive the benefits of the 2019 ANSI Standard’s heightened RF interference 
requirements, and we allow consumers who use telecoils to receive the benefits of the 2019 ANSI 
Standard’s improved inductive coupling requirements.75  In addition, the 2019 ANSI Standard offers 
other consumers benefits, including coverage of new technologies and devices, and an expanded 
frequency range.76  As commenters observe, granting the waiver request will allow consumers with

those related to volume control.77  
24.2N Force Level Conversational Gain Test.  With these benefits in mind, for the 
conversational gain test at the 2N force level we accept ATIS’s proposal as clarified in the ATIS Ex 
Parte Letter and condition this waiver on handsets having to pass testing using all available narrowband 
and wideband codecs and air interface combinations.78  Further, we require handset manufacturers to 
place the lowest conversational gain that results from this testing on the handset’s package label in a 
manner consistent with our hearing aid compatibility labeling rules.  This approach is consistent with 
ATIS’s waiver request.  It is also consistent with our package labeling requirements, which require the 
lowest conversational gain that results from testing the various combinations of narrowband and 
wideband codecs and air interfaces to be placed on the package label in order to avoid an inflated test 
result being placed on the label.79  In addition, commenters universally support ATIS’s 2N force level 
test proposal as well as all other aspects of ATIS’s waiver testing proposals.
25.8N Force Level Conversational Gain Test.  As ATIS suggests in the ATIS Ex Parte 
Letter, manufacturers will continue to be required to conduct the 8N force level conversational gain test, 
but we waive the requirement that the test achieve at least an 18 dB passing rate.80  Under this approach, 
manufacturers are required to perform the 8N force level test using the same testing parameters as 
established for the 2N force level test, and must place the resulting conversational gain (even if it is 
below 18 dB) on the handset’s package label in a manner consistent with our existing hearing aid 
compatibility labeling rules.81  This decision is consistent with one of the stated reasons that the 
Commission adopted a handset volume control requirement, which is not only to aid consumers with 
hearing loss who use hearing devices, but also to aid consumers with hearing loss who do not use 
hearing devices.82  The approach we adopt for the 8N force level test is consistent with this objective and 
gives consumers with hearing loss who do not use hearing aids the relevant information that they need to 
make informed handset purchasing decisions.
26.Distortion/Noise and Frequency Response Tests.  With respect to the related 
distortion/noise and frequency response tests at the 2N and 8N force levels, we accept ATIS’s 
suggestions set forth in the ATIS Ex Parte Letter.  Consistent with the ATIS Ex Parte Letter, we 
condition this waiver on handsets having to pass testing using at least one narrowband and one wideband 
codec of the manufacturer’s choosing.  Further, we accept ATIS’s suggestion that the chosen 
narrowband and wideband codecs will be tested using one bit rate and with only those air interfaces 
associated with the chosen codecs.83  We also accept ATIS’s suggestion that only the chosen narrowband 
and wideband codecs will be tested for distortion/noise and frequency response and the other codecs 
used for testing for conversational gain at the 2N and 8N force levels are not required to undergo the

78 The ATIS Ex Parte Letter clarifies that the 2N and 8N force level testing will be done on all available codecs and 
with all air interfaces, but in performing the conversational gain test as specified in the TIA 5050 Standard, these 
codecs are not required to undergo testing for distortion/noise and frequency response unless they are the specific 
codecs that manufacturers have chosen for the distortion/noise and frequency response tests.  ATIS Ex Parte Letter

83 ATIS states that testing over all bit rates as opposed to just one bit rate will “not benefit consumers because it 
would not create meaningfully helpful results.”  ATIS Ex Parte Letter at 3 & n.7.  Further, ATIS “notes that the 
magnetic testing for telecoil (which tests all bitrates) is a fundamentally different test than the audio testing being 
done for volume control.”  Id. (emphasis in original).Federal Communications Commission DA 23-914
11distortion/noise and frequency response tests.84  In this regard, we accept ATIS’s “alternative method” 
for determining the volume control setting for purposes of testing the other codecs for conversational 
gain and for reporting those test results consistent with that method.85
27. This approach follows the TIA 5050 Standard’s requirement that handsets pass testing 
using one narrowband and one wideband codec.86  This approach also gives assurance that a handset’s 
amplifier/speaker combination will meet consumer expectations over both narrowband and wideband 
modes of voice communications as envisioned by the current standard.  At the same time, our decision to 
accept ATIS’s proposed modification and allow manufacturers to choose which narrowband and 
wideband codecs to test gives manufacturers more flexibility than the TIA 5050 Standard, which 
specifies the narrowband and wideband codecs to be tested.  We accept ATIS’s suggestion on this point 
given the testing methodology flaw seen when testing an AMR codec.
28. ATIS’s proposal to give manufacturers flexibility to choose any codec for testing appears 
linked to the data in the HAC Task Force’s Final Report that handsets cannot pass the distortion/noise 
and frequency response tests using certain codecs.  In particular, the data relied upon by ATIS indicates 
that handsets cannot pass the distortion/noise test when tested using the AMR codecs specified in the 
TIA 5050 Standard.87  ATIS asserts that the developers of the TIA 5050 Standard did not attempt to 
resolve the technical difficulty of developing a test signal with speech-like characteristics that could pass 
substantially unchanged through all possible speech codecs or that would evaluate the end-to-end 
transparency of the various speech codecs.88
29. The HAC Task Force’s Final Report, however, includes data from two unnamed 
manufacturers indicating that four of their handsets were able to pass the distortion/noise part of the 
volume control testing standard using an EVS wideband codec as opposed to an AMR wideband codec.89  
We are concerned that if manufacturers choose to test just narrowband codecs, the tested handsets will 
fail to demonstrate the performance of their speaker/amplifier combinations when a wideband voice 
codec is used.  As a result, for the distortion/noise and frequency response tests at the 2N and 8N force 
level, rather than requiring testing of both narrowband and wideband AMR codecs, as generally required 
by the TIA 5050 Standard, we require that handsets pass testing of at least one narrowband codec and 
one wideband codec of the manufacturer’s choosing, as discussed above.
30. For the distortion/noise and frequency response tests at the 2N and 8N force levels, 
manufacturers must choose codecs that are within the scope of the TIA 5050 Standard, which include 
narrowband and wideband codecs, but these codecs do not necessarily have to be AMR codecs.  That is, 
we are not limiting the codecs that manufacturers can choose for testing to just AMR narrowband and 
84 Id. at 2 & n.5.
85 Under ATIS’s alternative method for testing the other codecs when it performs conversational gain testing, a 
manufacturer will first establish the volume control setting by conducting the full set of tests for the selected 
narrowband and wideband codecs.  The manufacturer will then use this adjusted volume control setting for purposes 
of testing the other codecs and air interfaces for conversational gain at the 2N and 8N force levels.  Id.  This more 
conservative approach is preferable to the other approach ATIS suggests which is to test the other codecs and air 
interfaces without first determining the volume control adjustment.  Id.  Determining the volume control adjustment 
first—as part of the complete test for at least one narrowband and one wideband codec selected for distortion/noise 
and frequency response testing—before testing the other codecs and air interfaces may lead to more accurate 
conversational gain test results for these other codecs.

12AMR wideband codecs as defined in sections 4.5.1 and 4.5.2 of the TIA 5050 Standard.  While 
manufacturers may choose to test AMR narrowband and AMR wideband codecs, they can also choose 
EVS narrowband and EVS wideband codecs or any other narrowband or wideband codecs that are 
within the scope of the TIA 5050 Standard.  If a handset does not have a wideband codec or the handset 
only has an AMR wideband codec, then the test report must document this fact and the passing 
requirement under these circumstances for the wideband codec test is waived.  The passing results for 
the distortion/noise and frequency response tests must be reported in the handset’s test report.
31.Revised Volume Control KDB Guidance.  To help in this matter, OET, in coordination 
with WTB, will issue a revised KDB guidance document for volume control testing consistent with this 
Order.90  This revised KDB guidance will address the technical testing requirements for the 
conversational gain, distortion/noise, and frequency response requirements that are part of the conditions 
of this Order.  The KDB guidance will also address the reporting requirements for the test data required 
under the conditions of this Order.  Manufacturers and testing laboratories are expected to fully follow 
the KDB guidance’s testing instructions as issued.  These testing requirements are to ensure the best 
listening experience for consumers with hearing loss as possible under the waiver we grant today.
32.Labeling Requirements.  We remind handset manufacturers that our hearing aid 
compatibility labeling rules require certain information to be placed on a handset’s package label and 
additional information be provided in the handset’s package insert and user manual.91  Our handset 
package labeling rules require that a handset that is certified as hearing aid-compatible state on the 
handset’s package label that the handset is hearing aid-compatible.  In addition, if the handset is certified 
under a standard that includes volume control requirements, such as under the 2019 ANSI Standard, the 
label must specify the handset’s conversational gain with and without hearing aids.92  These 
requirements give consumers the most pertinent information on a handset’s package label and allow 
consumers to determine if the conversational gain of the handset meets their needs.93
33. In addition, for handsets certified as meeting volume control testing requirements, our 
rules require that package inserts and user manuals for these kinds of handsets provide an explanation of 
the handset’s volume control capabilities and how special testing circumstances such as those permitted 
by this Order affect those functions.94  Consumers must have this information to ensure they can 
purchase handsets that best meet their individual needs.  Since we are waiving certain aspects of the all 
air interface/frequency/codec volume control testing approach, consumers must be informed as to how 
this change affects the volume control capabilities of a handset they are considering that has been 
certified as hearing aid-compatible under the conditions of this Order.  We require package inserts and 
user manuals for these type of handsets to state which codecs and air interface combinations were used 
to pass testing for conversational gain and for the related distortion/noise and frequency response tests 
and which codecs and air interfaces were not tested.  Consumers must be able to understand the volume 
control capabilities of tested operations and non-tested operations and what this means in terms of the 
volume control differences between the two types of operations.95
90 See supra n. 64 (defining a KDB guidance document).  The revised KDB guidance will be available through 
OET’s KDB website using Publication Number 285076.  See https://apps.fcc.gov/oetcf/kdb/.

1334.Benchmark Compliance.  Pursuant to this Order, we allow handsets that pass the volume 
control testing requirements set forth above, as well as the rest of the 2019 ANSI Standard’s testing 
requirements, to be certified as hearing aid-compatible under the 2019 ANSI Standard and the related 
TIA 5050 Standard.  Handsets that satisfy all of these requirements may be marketed as meeting the 
Commission’s hearing aid compatibility requirements and counted as hearing aid-compatible for 
benchmark deployment purposes.  The same is true for handsets that meet the above testing requirements 
through the permissive change process.  These types of handsets can also be marketed as meeting the 
Commission’s hearing aid compatibility requirements and counted as hearing aid-compatible for 
benchmark deployment purposes.  Handset manufacturers, however, must continue to comply with all 
other aspects of our wireless hearing aid compatibility rules, including labeling, website posting, and 
reporting requirements.
35. During the remainder of the exclusive use transition period that ends on December 5, 
2023, handset manufacturers may continue to certify handsets as hearing aid-compatible using either the 
2011 ANSI Standard or the 2019 ANSI Standard as conditioned by this Order.96  Handsets certified as 
hearing aid-compatible under either of these standards may be counted for benchmark deployment 
purposes.  Consistent with established practice, however, handset manufacturers must use one or the 
other standard for certification purposes and may not mix parts of each standard.97  After December 5, 
2023, handset manufacturers may only certify new handsets as hearing aid-compatible using the 2019 
ANSI Standard as conditioned by this Order.
36.Waiver Time Limit.  The waiver we adopt today becomes effective upon the release date 
of this Order and will continue to be effective for a two-year period after the release date of this Order.  
ATIS and commenters have indicated that a new volume control standard is being developed through the 
TIA process and that they expect the process to move quickly in order to make the new standard 
available to the Commission to make effective.98  We plan to hold parties to this commitment, and we 
expect parties to expedite the process for developing a new volume control standard in time for the 
Commission to adopt the new standard prior to the waiver period expiring.  In order to meet this 
objective, we encourage parties to work rapidly and cooperatively for the benefit of consumers with 
hearing loss.
37. We further condition this Order on ATIS filing with us a letter on the one-year 
anniversary of the release date of this Order.  This letter must appraise the Commission on the status of 
the development of a new volume control standard and any issues that have arisen with respect to the 
establishment of the new standard.  Further, the letter must inform us as to when the new standard will 
be made available to the Commission for adoption.  This letter should be seen as an opportunity for 
ATIS to inform the Commission that parties are on track to petition the Commission to adopt the new 
standard prior to the waiver period expiring.
38. We find that our actions today are not only in the public interest but also fully consistent 
with the underlying purpose of our wireless hearing aid compatibility rules.  These rules are based on the 
principle that consumers with hearing loss should have the same access to the newest and most advanced 
handsets as consumers without hearing loss.99  By waiving certain handset testing requirements under the 
conditions of this Order, we ensure that the underlying purpose of our hearing aid compatibility rules is 
not frustrated.  This Order allows new handsets to be certified under the 2019 ANSI Standard and 
consumers with hearing loss will be able to enjoy the benefits that these new handsets will be designed

14to offer.  In addition, our decision permits handset manufacturers to be able to certify new handsets as 
hearing aid-compatible after the exclusive use transition period ends this coming December.  As such, 
our actions today are consistent with the underlying purpose of our hearing aid compatibility rules and 
avoid that purpose from being frustrated by strict adherence to the volume control testing requirements.  
In view of the unique and unusual factual circumstances of this case, we find that strict application of the 
volume control testing requirements would be contrary to the public interest.
39. Finally, our decision is consistent with our goal of requiring all new handsets to be 
certified as hearing aid-compatible.100  We are encouraged by the members of the HAC Task Force 
reiterating “their commitment to working towards the goal that all new handsets will meet HAC 
requirements,” including “an applicable volume control standard.”101  We continue to strive toward our 
goal of 100% hearing aid compatibility in the near future and our decision to conditionally waive certain 
aspects of our volume control testing requirements as discussed above is consistent with this objective.  
Our decision allows handset manufacturers to continue the process of certifying all of their handsets as 
hearing aid-compatible, as many currently do.102
